Cycling and the Challenge of Interval Swimming

Today I varied things a little. I went for a 14 mile bike ride this morning and then switched up my endurance swimming for some lung busting intervals in the pool. As the weather gets warmer and the evenings get lighter it is getting harder for me to resist the pull of cycling over all other forms of exercise so I am trying to add variation to spice things up.

The ride was 14 miles, and I intended to push to 20 and include a 30 degree climb, however I decided to leave enough in the tank to swim tonight.

Interval swimming is very challenging. Tonight I did intervals of 8, 6, 4 and 2 laps, although I accidentally did 10 for the first set. I absolutely hammered away as hard as possible, averaging at 1 minute 41 seconds per 100 metres. I thought my heart would explode out of my chest. I worked as hard as I could physically stand. Now that I have hit Iron Man distances for endurance swimming I returned to intervals for the serious business of fat burning and speed.
